Don’t bother with Thermarest, get this!

Like everyone wise getting into camping you watch a few vids and soon see everyone using that bright yellow Thermarest Z-Lite mat which is a great mat but if you’ve seen this you’re in for a bargain. It’s half the price and it’s get a ever so slightly better R-value and having laod on both it’s no different in comfort. This mat is simply awesome for the money and for adding that extra layer of insulation from the cold ground. Better still, if your vertically challenged like myself at a mere 5’3” you can cut the bottom two sections off and use it as a very generous sit-mat too. Win win. In conclusion. If you’re looking for an insulated foam mat for camping get this and save ya money from the pricier names and use that saving for something else.(nice coffee instead)

Good quality technical mattress

This looks a good technical folding mattress but not comfortable for side sleepers so I will cut it and use it for another purpose

Long & wide enough with reflective heat side 2.5R

A good quality, good value mat that weighs little - if too long easy to 'cut down' Folds so easily and waffle eggbox construction is comfortable. Good for 3 season use - There is one side, heat reflective silver which you lie on to reflect most heat back to your body and the other side is blue The folded mat is held by x2 supplied elastic webbing straps

не достатъчно добра

не е достатъчно плътна пяната, направо е мека при тестване направо на земята се проби от сухата трева, плътността е като на иога постелка, надали ще издарже повече от седмица, продължавам да мисля че декатлон не тества реално продуктите си, очаквах да е доста по плътна при положение че е сгъната а не навита, очаквах да е по сздражлива и чрез нея да компенсирам неравностите на терена и върхунея да ползвам самонадуваема постелка, като плюс мога добавя че е лека, компактна и с много добра топло сзолация, но явно под нея е нужен някакав дебел и плътен бризент

Karimatka vhodná pouze do hamaky

Pro spaní na zemi velmi nepohodlná a měkká. Po 4 dnech jsem byl velice rozlámaný. Pro nouzové přespání dostačující.

Additional Product Information



  • 100% Foamed polyethylen

Volume and folded size

Folded size 5.9" x 5.5" x 21.7". Elastic support. 12.4 liter volume. Weight including the pack: 1.1 lbs Density of the foam 65 lbs/m³. Dual-fabric foam.

Thermal protection and heat

Since the beginning of 2020, a new standard has been validated to assess the level of insulation of your mattress: standard ASTM F3340-18. This standard measures the capacity of the mattress to retain or return body heat in order to avoid its loss and therefore provide you with thermal comfort. Thermal insulation provided by the foam. R-Value standard ASTM F3340-18 insulating mattress Trek 100 foam: 2.2 (measured by an independent laboratory)

Thermal properties and warmth (2)

The R-Value expresses the thermal performance and resistance of the mattress. The higher the R-Value, the more the mattress insulates you from the cold ground. - R-value from 0 to 1.9: mattress designed for use in warm season (summer) only - from 2 to 3: mattress designed for use in 2 or 3 seasons (spring/summer/autumn) - from 3 to 4: 4-season mattress, winter use possible - higher than 4.5: winter use and extreme conditions

Comfortable postural support

Sleep on aluminized side, facing the sleeping bag with foam side on the ground to minimize losses of body heat. Because of the design and the depth given to the foam by the mold, this mattress offers a greater level of comfort than other foam mattresses. This specific design allows for 0.8" mattress thickness, giving home comfort and real postural support.
